Find the Runner-Up Score!

  Given the participants' score sheet for your University Sports Day, you are required to find the runner-up score. You are given     scores. Store them in a list and find the score of the runner-up. Input Format The first line contains  . The second line contains an array     of   integers each separated by a space. Constraints Output Format Print the runner-up score. Sample Input 0 5 2 3 6 6 5 Sample Output 0 5 Explanation 0 Given list is  . The maximum score is  , second maximum is  . Hence, we print   as the runner-up score. ### OPTIMIZED ### from   collections   import   Counter if  __ name__  ==  '__main__' :      n  =  int ( input ())      arr  =  map ( int ,   input () . split ())           lis = list ( Counter ( arr ) . keys ())      lis . sort ()  ...

Print All Substrings

  For a given input string(str), write a function to print all the possible substrings. Substring A substring is a contiguous sequence of characters within a string. Example: "cod" is a substring of "coding". Whereas, "cdng" is not as the characters taken are not contiguous Input Format: The first and only line of input contains a string without any leading and trailing spaces. All the characters in the string would be in lower case. Output Format: Print the total number of substrings possible, where every substring is printed on a single line and hence the total number of output lines will be equal to the total number of substrings. Note: The order in which the substrings are printed, does not matter. Constraints: 0 <= N <= 10^6 Where N is the length of the input string. Time Limit: 1 second Sample Input 1: abc Sample Output 1: a ab abc b bc c  Sample Input 2: co Sample Output 2: c co o #include <iostream> #include <cstring> us...
